SDSS 1355+0856: A detached white dwarf + M star binary in the period gap discovered by the SWARMS survey
Carles Badenes, Marten H. van Kerkwijk, Mukremin Kilic +5
SDSS 1355+0856 was identified as a hot white dwarf (WD) with a binary companion from time-resolved SDSS spectroscopy as part of the ongoing SWARMS survey. Follow-up observations wi…
The metrology cameras for Subaru PFS and FMOS
Shiang-Yu Wang, Yen-Shan Hu, Chi-Hung Yan +11
The Prime Focus Spectrograph (PFS) is a new multi-fiber spectrograph on Subaru telescope. PFS will cover around 1.4 degree diameter field with ~2400 fibers. To ensure precise posit…
Prime Focus Spectrograph - Subaru's future -
Hajime Sugai, Hiroshi Karoji, Naruhisa Takato +51
The Prime Focus Spectrograph (PFS) of the Subaru Measurement of Images and Redshifts (SuMIRe) project has been endorsed by Japanese community as one of the main future instruments…
Subaru weak-lensing measurement of a z = 0.81 cluster discovered by the Atacama Cosmology Telescope Survey
Hironao Miyatake, Atsushi J. Nishizawa, Masahiro Takada +25
We present a Subaru weak lensing measurement of ACT-CL J0022.2-0036, one of the most luminous, high-redshift (z=0.81) Sunyaev-Zel'dovich (SZ) clusters discovered in the 268 deg^2 e…
Characterizing the Galactic White Dwarf Binary Population with Sparsely Sampled Radial Velocity Data
Dan Maoz, Carles Badenes, Steven J. Bickerton
We present a method to characterize statistically the parameters of a detached binary sample - binary fraction, separation distribution, and mass ratio distribution - using noisy r…
Regularization Techniques for PSF-Matching Kernels. I. Choice of Kernel Basis
A. C. Becker, D. Homrighausen, A. J. Connolly +4
We review current methods for building PSF-matching kernels for the purposes of image subtraction or coaddition. Such methods use a linear decomposition of the kernel on a series o…
